This may seem like a pipe dream to some, but it is a reality that some companies strive to achieve.</p><p style=";text-align:left;direction:ltr"> This was evident with the launch of the new generation of smart phones from some companies that supported their devices with wireless charging.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> The idea of wireless electricity is not new. At the beginning of the twentieth century, the scientist Nikola Tesla tried to build towers that transmit electricity between them wirelessly, but the attempts of scientists in the past years succeeded in generating a magnetic field between two parties with a distance of several meters between them on the principle of electromagnetic resonance.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> Despite the amounts that can be saved by dispensing with electrical wires, the dilemmas facing this technology must first be overcome, the most important of which seem to be limited to the weakness of the range it provides, and the electric power that is generated by wireless electricity, in addition to the health effects of the environment in which the current passes. electrocution, which has not been shown to be sufficiently secure.</p><p style=";text-align:left;direction:ltr"></p>
